ABSTRACT:
A coupling for electric motors, with each motor comprising a rotor (62, 63) and a stator (60, 61) mounted in a tubular shell (4, 5). The coupling includes the ends (8, 8a) of the tubular shells to be assembled, shaped for end-to-end inter-fitting in a manner which determines a relative angular position of the shells, the shape being identical on both shells; the coupling further including an internal coupling module (12) constituting a subassembly which is independent of the motors per se. The module comprises a coupling sleeve (15) for coupling the rotor shafts (16, 17), electrical connection means (29) for interconnecting the stators (60, 61), and support means acting both as radial bearings (19, 20) and as axial stops (21, 22) for the motors. The end of at least one of the rotor shafts to be coupled in rotation has a coupling section defined by the surface inside a closed, non-circular line having polar co-ordinates such that the polar radius is periodic over an angle equal to 2
, where n is a positive integer greater than one, and the sleeve has at least one end with a corresponding bore. The ends of the sleeve and of the shaft further include respective conjugate inlet shapes enabling the shaft to penetrate into the sleeve regardless of their relative angular positions by virtue of a force which is solely axial, causing at least one of the two parts to rotate until both parts are correctly oriented relative to each other. The coupling further includes link means (11, 11a) between the internal coupling module (12) and the shells (4, 5).
